High Speed Cut To Length Blanking Line

What Is Cut To Length Line?

Cut to length machine, cut to length blanking line is an automated production line used to process metal coils into plates of specific lengths, and is widely used in industries such as steel, automobiles, home appliances, and construction. Cut to length line is a special shearing blanking line device that processes continuous metal coils into the size required by customers by flattening and then cutting to length. The cut to length line consists of uncoiling, flattening, NC sizing, flying shears, and material collection mechanisms, supplemented by material transport, buffering, guiding, conveying, and discharging devices.

Type Of Cut To Length Line By Devices

The cut-to-length shearing line will have different cut-to-length shearing line production solutions according to the raw materials, thickness, width and production and processing requirements of the coils to be processed, helping customers achieve high-quality metal sheet processing technology. From the perspective of different configurations, the cut-to-length shearing line will be divided into the following categories:

1/Cut To Length Machine With Dual Straightener

Equipped with two levelers in the Cut to Length Line, it can eliminate the stress of metal sheets in stages, improve the leveling accuracy and adapt to different material properties, ensuring that the sheared sheets meet higher quality requirements. Generally speaking, the Cut to Length Machine uses five-roller or six-roller rough adjustment leveling rollers to quickly eliminate the large deformation and surface wrinkles of the coil. Through the high-precision leveling rollers with a two-stage nine-roller or ten-roller structure, the sheet is fine-tuned to eliminate residual stress and ensure the flatness error of the sheet

The Cut to Length Line equipped with double levelers is widely used in the fields of automobiles, home appliances, new energy, precision manufacturing, etc. Its staged leveling technology solves the industry pain points of stress release of high-strength materials and deformation control of ultra-thin materials, while meeting the needs of efficient production and high-precision processing.

2/Cut To Length Line With Pit System

KINGREAL SLITTING cut to length machine pit system plays the role of a dynamic balancer in the Cut to Length Line. Through material storage, tension adjustment and process connection, it solves the problems of material fluctuation, precision loss and equipment loss in high-speed production. The Pit System forms a dynamic storage area between the uncoiler and subsequent processing equipment through the Looping Pit or storage pit design. When the speed of the front and back sections of the production line is inconsistent, the Looping Pit can automatically adjust the material storage amount to avoid material accumulation or material breakage caused by speed difference.

During the unwinding process, metal coils are prone to shaking or speed fluctuations due to inertia. The Pit System uses gravity droop or material storage racks to balance the tension, reducing the lateral deviation of the material during the feeding stage, thereby improving the fixed-length shearing accuracy. For easily scratched materials such as stainless steel and aluminum, the flexible transition design of the loop pit in the cut to length line can avoid direct friction between the material surface and hard parts.

3/Cut To Length Machine With Auto Stack

In the Cut to Length Line, automatic stacking is the core link to improve production efficiency, ensure the quality of finished products, and reduce labor costs. It can help improve the efficiency and control costs of the cut to length production line. Through precise stacking and material protection, it can ensure that the finished products meet the high standards of the automotive, home appliance, new energy and other industries.

According to the actual production needs of customers, KINGREAL SLITTING can provide different types of automatic stacking devices and dual stack devices to meet the actual processing and production needs of customers for metal sheets.

Why Choose High Speed Cut To Length Blanking Line?

High-speed Cut to Length Blanking Line is an upgraded version of the traditional fixed-length cutting line. It is designed to meet the needs of large-scale, high-efficiency and high-precision metal sheet processing, especially for industries with strict requirements on production speed and cutting accuracy.

1/High speed cut to length line decoiler system

The unwinding system of the high-speed Cut to Length Line is a key module for achieving continuous and efficient production, and its design directly affects the stability of material transportation. In the unwinding system of the high-speed cut to length machine, the loading trolley is responsible for accurate loading through automatic positioning and lifting. The car body is lifted vertically by the lifting cylinder, and the guide column and guide sleeve cooperate to ensure the lifting stability. Dual hydraulic decoiler can help the high-speed cut to length line improve the efficiency of coil change. The main coil and the spare coil work alternately, and the switching time is ≤30 seconds. It is particularly suitable for high-frequency coil change scenarios such as silicon steel and new energy vehicle plates.

At the same time, it is also equipped with an unwinding auxiliary support arm. The support arm is linked with the sliding sleeve through a slewing bearing, and the concave arc cylindrical support roller fits the outer diameter of the roll, reducing contact stress to solve the risks of spindle deflection and tower roll.

Load-bearing capacity: 30T

Inner diameter of steel coil: Φ508mm; Φ610 mm; Φ760 mm

Outer diameter of steel coil: MAX: Φ2200mm

Arc plate structure of unwinding drum: Opening and closing gear box structure

Expansion and contraction range of arc plate: Φ470mm-Φ760mm

2/ Six-layer leveler for cut to length machine

The six-layer leveler is the core equipment in the cut to length line. It uses multiple sets of rollers to level the metal coils with high precision, eliminate the internal stress of the material and improve the surface quality.

The six-layer leveler adopts three rows of rollers arranged in an alternating manner to form a six-layer structure. The upper row of working rollers adjusts the downward pressure through hydraulic pressure or screws, and the support rollers are distributed between the working rollers to enhance rigidity and reduce flexural deformation. It helps to eliminate defects such as wavy lines and transverse bows in the coils during the cut to length process.

Number/diameter of leveling rollers: 21pcs×Φ70mm

Material of leveling rollers: 9Cr2Mo

Type of leveling rollers: Six-layer roller type

Intermediate rollers: 23pcs×Φ70mm

Support rollers: 5 groups each upper and lower 105pcs×Φ80mm

Pinch rollers: 2pcs×Φ156mm (rubber roller)

3/ Fly-shearing machine for cut to length line

High-speed flying shears are important equipment in the cut to length line, which are specially used for high-precision and high-efficiency transverse shearing of metal strips on high-speed continuous production lines. Its design goal is to achieve non-stop shearing of materials in motion through dynamic synchronization technology, thereby greatly improving production efficiency and finished product quality.

High-speed flying shears achieve continuous material processing through dynamic synchronous shearing. The horizontal component speed of the shearing tool matches the transmission speed of the strip in real time to ensure that there is no relative sliding at the moment of shearing. It can help the processing speed of the cut to length line reach 60-80M/min. Generally speaking, the common metal shearing speed on the market is 30-50M/Min.
